S = e^ix - (1/2)e^3ix + (1/4)e^5ix - … is an infinite geometric series, equal to a/(1 - r). a = e^ix and r = (1/2)e^2ix thus S = e^ix/(1+(1/2)e...

The neuromuscular junction describes the chemical connection between a presynaptic nerve, and the muscle fibre membrane (sarcolemma). Depolarisation of the presynaptic nerve membrane (by propagation of an...

To find stationary points, we need to find dy/dx and set it equal to 0. Here we must use implicit differentiation: d/dx(x²) + d/dx(-xy) + d/dx(y²) = d/dx(12). Hence 2x - x(dy/dx) - y...

The nucleus contains positively charged protons which attract the negative electrons, the first ionisation energy is the energy required to overcome this attraction and remove 1 electron As you go down a ...

I will prepare various questions based on their personal statement, and depending on if the interview they are preparing for is MMI or panel style, I will prepare several stations each looking for differe...
